A rights managing model in learning resource distribution

In this paper, we present a rights managing model to establish rights management in learning resource distribution, and elaborate how it facilitates the rights delegation, which is very common in e-learning. The rights managing model covers both the basic aspects in digital rights management and the characteristic points in learning resource distribution. Important issues of rights delegation and secondary license issuing are addressed in this paper. We focus on these two problems by designing a flexible rights managing model consisting of a safe kernel, a control set and a verifying center, and an extended license is also defined to enforce the more convenient rights granting process in the model.
